Abstract: A tire surface managing method, comprising: emitting detecting light to a target object on a surface of a tire; receiving reflected detecting light from the target object and from the surface adjacent to the target object; determining whether the target object protrudes according to a distance calculated according to the reflected detecting light from the target object and a distance calculated according to the reflected detecting light from the surface; determining whether the target object forms a hole on the surface according to the distance calculated according to the reflected detecting light from the target object and the distance calculated according to the reflected detecting light from the surface; receiving the reflected detecting light from the surface to calculate a width of the hole on the tire; and activating a protection mechanism for a vehicle comprising the tire if the width is larger than a width threshold.

Abstract: An object surface managing method comprising: (a) emitting detecting light to the groove via alight source; (b) receiving first reflected detecting light from the surface and second reflected detecting light from a bottom of the groove via a light sensor; and (c) calculating a groove depth of the groove according to the first reflected detecting light and the second reflected detecting light.
